ASSIG-NOR- T LOVELL MANUFAC- CORPORATION PENNSYLVANIA WRINGER Application filed July 6, 1925.

It is desirable in the formation of wringers, particularly such .wringers as are used for power washers to provide them with a rigid frame. One reason for this is that most of such wringers are supported at one end of the frame so that they may be swung into and out of position. The present invention is designed in a simple and ,con-

venient manner to form the frame of greater then is ordinarily possible and arrange it so that the parts may be readily removed or detached for renewal. The invention also contemplates an improvement in the safety release device with which the.

The invention also contemplates an improved means for locking a reversible drip board in its operative position. Other features and details of theinvention will appear-from the specification 20 and claim.

The invention is illustrated in the accom panying drawings as follows 2- Fig. 1 shows a front elevation of the wringer.

Fig. 2 an end elevation.

Fig. 3 a sectional view of the wringer with the parts partially detached showing a-method of assembly.-

Fig. 4 aplan view of the frame with the a Fig. 5a view of the cam mechanism of the safety release, being in section on the line 5-5 in Fig. 1.

The wringer frame is cast in one piece and 1 of box sect1on connected by the bottom bar 2 and top bars 3, the top bars 3 Serial No. 41,568.

end provided with a driving socket 12 and its gear end provided with a gear is assembled as shown in Fig. 3 by putting the driving end through the perforation 6a, moving the gear 13 through the top end of the gear box, the 'rod extending down between the ribs 5 and 7. The rod rests in the journals 10a which rest on the bottoms 4a of the stiles. An upper rod 14 carries an upper roll 15 and is provided with a gear 16 meshing with the gear 13. It is assembled by moving-directly down in a verticaldirection, the roll passing between the plates 3 and the rod between the ribs on the opposite faces of the stile, the gear moving into the gear box through its upper open end. Bearings 17 are slipped into the open upper ends ofthe guides 4 into position on the top of'the rod 14 and a tension spring 18 is placed between the ribs 5 on top of the bearing block 17. A detachable top- 19 ispro vided. The upper ends of the stiles 1 have. ears 20 and the top 19 has perforated ears 21 which extend over the ears 20 and a hinge pin 22 extends through the perforations in being in the form of plates at the front and back face of the.

frame leaving an opening 4 through the top.

The stiles are hollow having guide openings to bottom of these.

4 .extending from top stiles with inwardly extending ribs 5. along the insides of the guides. At the driving end of the roll the outer wall of the stile is closed at 6 with a perforation 6a, for the drive shaft. At the gear side of the rolls ribs 7 extend inwardly from the face walls and a gear box8 is formed on the end face of the stile.

roll 11 has its driving 20 and 21 hinging the top in place At the opposite end a pin 23 is provided with a thumb nut 23a. which permits of its ready removal so that the top may be swung up to the position shown in Fig. 3 to permit the detachment of the rolls, or different parts of the wringer. The top forms a housing covering all the openings in the top of the wringer, the top being hollow so as to permit the upper part of the spring 18 to extendinto it. The top has an extension 24 which extends over and closes the top of the gear box.

' A release bar 19a has a depending sleeve the ears 1% which extends through an opening 190 I The perforation 190 has axial slots 19d 19a slide, the projections 190 operating upon cams 19f on the under side of the top bar. A tension screw 199 extends through the sleeve 1% into a socket 19h on the tension bar. The cams 19f are formed of a separate piece as malleable iron and are secured in the top bar, which is ordinarily made of aluminum, in the casting operation as shown in section in Fig. 5. This gives a bearing surface of sufiicient hardness to sustain the pressure of the projections 196 in a simple and efiicient manner. -Heretofore the entire 4 6 sleeve has ordinarily been secured to the top of an aluminum top bar making a rather unsightly construction and also one requiring extra finishing to make it match the aluminum structure.

w The details of the release mechanism, other than the forming of the cam block,

15 the lower ends of the side stiles and a drain board 26 has aflange 27 which operates on the pin 25, the flange being provided with the small sockets 28 and stops 29 to limit its movement to each reverse position. Difii- :o culty has been experienced in securely locking this board in a simple and eliicient manner in its reversed positions. This is acears 31 by means of pins 32. The finger 30 has its bottom eccentrically formed relatively to the pivot, forming a camming engagement with the drip' board as it is swung on its pivot-against the drip board,

' 30 the drip board restlng on the pins 25 and the bottom bar 2 being engaged between these two points of support by the .cam finger 30 securely locks it in this position, the tendency of the cam finger being to wedge itself 3 against the board and tighten with any movement of the board.

at I claim as new is In a wringer, the combination of a frame comprising side stiles and a bottom bar, the sidestiles having guideways, one of said side stiles having the upper part of the outer face of the guide-way closed and provided with a shaft perforation; and wringer rolls mounted in the frame, one of said rolls havwringer, said rolls being insertable from the top of the wringer. In testimony whereof I have hereunto set .my hand.
